Gravity Sewer Systems
5.5 Uponor PVC Sewer System The Uponor PVC Sewer System is designed for standard storm- and wastewater gravity sewer applications. Its smooth, single-wall pipes are made of polyvinyl chloride (PVC) and have a ring stiffness class of SN 8. The pipes have terra cotta colouration for easy identification as sewer pipes. Pipes and fittings are made of terra cotta coloured polypropylene (PP). Fittings for pipes with a diameter greater than 200 mm are made of terra cotta coloured PVC. All pipe fittings have a ring stiffness of SN 8. All pipes and fittings come equipped with pre-installed seals for guaranteed joint tightness. System and material specifications Properties
